After 25 minutes of CPR for an unwitnessed arrest with PEA, what is the next priority if ROSC is achieved?

The correct answer is the rapid transport to a Stroke Receiving Center, especially in the context of an unwitnessed arrest with pulseless electrical activity (PEA). If Return of Spontaneous Circulation (ROSC) is achieved after prolonged CPR, it is critical to assess the patient's neurological status and determine if their cardiac arrest may have been caused by an underlying condition such as a stroke.

Transporting to a Stroke Receiving Center allows for swift access to specialized stroke care, which may include advanced imaging and potential interventions like thrombolysis. Timely treatment in stroke cases can significantly improve outcomes.

In circumstances where ROSC has been achieved after extended resuscitation efforts, priorities shift to stabilizing the patient and addressing any underlying causes of the cardiac arrest. Therefore, ensuring the patient receives appropriate care in a facility equipped to handle potential stroke cases is vital.

Other options like the administration of epinephrine, initiation of chest compressions, or intubation may not be the immediate priority at this stage. While epinephrine can be critical during arrest situations and airway management might be necessary, the focus following ROSC should be on rapid transport and appropriate post-arrest care, including evaluating for conditions like stroke.
